Magnetar
- A magnetar is a type of neutron star believed to have an extremely powerful magnetic field (∼109 to 1011 T, ∼1013 to 1015 G).
- Like other neutron stars, magnetars are around 20 kilometres (12 mi) in diameter, and have a mass about 1.4 solar masses.
What is the most powerful thing in the universe?
gamma-ray bursts
These explosions generate beams of high-energy radiation, called gamma-ray bursts (GRBs), which are considered by astronomers to be the most powerful thing in the universe.
What is the weakest star in the universe?
red dwarf star
The smallest known star right now is OGLE-TR-122b, a red dwarf star that’s part of a binary stellar system. This red dwarf the smallest star to ever have its radius accurately measured; 0.12 solar radii.
What is the rarest star in the universe?
Each is classified as an O-type star — and O-type stars are the rarest main sequence stars in the universe, comprising just 0.00003% of known stars. They’re extremely prone to going supernova and collapsing into black holes or neutron stars.
What can destroy a black hole?
The only known ways to “destroy” a black hole is to:
- have it merge with another one which turns 2 black holes into 1 black hole, so it is not really “destroyed”
- or wait up to for the black hole to evaporate all by itself through Hawking radiation. (See What would we see if we could watch as the universe is dying?
Who is the most powerful God in the universe?
Shiva is also considered as the God of Gods. The existence which represents infinity itself. He is the supreme masculine divinity in this universe and is lord of the three worlds (Vishwanath) and is second to none in wrath and power.
What star color is the hottest?
Blue stars
White stars are hotter than red and yellow. Blue stars are the hottest stars of all.
Is Jupiter a failed star?
“Jupiter is called a failed star because it is made of the same elements (hydrogen and helium) as is the Sun, but it is not massive enough to have the internal pressure and temperature necessary to cause hydrogen to fuse to helium, the energy source that powers the sun and most other stars.
What is the closest star to Earth?
Distance Information
Proxima Centauri, the closest star to our own, is still 40,208,000,000,000 km away. (Or about 268,770 AU.)
What is the oldest thing in the universe?
Astronomers have confirmed the discovery of one the oldest and most distant objects ever known in the universe — a star-forming galaxy 12.8 billion light-years away that started forming within a billion years of the Big Bang that kickstarted everything.
What is the rarest thing that can happen in the universe?
The breakthrough discovery was made by scientists who worked with a special instrument, built to track down dark matter, the most elusive particle in the universe. The all-important event was the radioactive decay of xenon-124. “We actually saw this decay happen.
What is the rarest galaxy?
The largest and rarest of these, called giant ellipticals, are about 300,000 light-years across. Astronomers theorize that these are formed by the mergers of smaller galaxies. Much more common are dwarf ellipticals, which are only a few thousand light-years wide.
Can a wormhole exist?
Einstein’s theory of general relativity mathematically predicts the existence of wormholes, but none have been discovered to date. A negative mass wormhole might be spotted by the way its gravity affects light that passes by.
What is a white black hole?
White holes are theoretical cosmic regions that function in the opposite way to black holes. Just as nothing can escape a black hole, nothing can enter a white hole. White holes were long thought to be a figment of general relativity born from the same equations as their collapsed star brethren, black holes.
Can a black hole swallow a galaxy?
There is no way a black hole would eat an entire galaxy. The gravitational reach of supermassive black holes contained in the middle of galaxies is large, but not nearly large enough for eating the whole galaxy.

Can there be a purple star?
Green and purple stars do exist. The color of stars depends on their temperatures, and they emit radiation throughout the visible spectrum. But when a star emits peak radiation at a wavelength we define as green, it also emits radiation over the rest of the spectrum.
What does Obafgkm stand for?

What color is the moon?
But despite this first-glance appearance, the moon isn’t exactly yellow nor bright white. It’s more of a dark grey, mixed in with some white, black, and even a bit of orange — and all this is caused by its geology.
